有一个库叫做aiomysql,这是一个基于asyncio和pymysql的库。至于为什么可以在tornado中使用,是因为高版本tornado的底层使用了asyncio。
import asyncio import aiomysql async def test(loop): # 这里的loop就是我们通过asyncio.get_event_loop()创建的,但是其实可以不传,因为会自动创建一个 async with aiomysql.create_pool(host="localhost", port=3306, user="root", password="zgghyys123", db="satori", loop=loop) as pool: async with pool.acquire() as conn: async with conn.cursor() as cursor: await cursor.execute("select * from girl") data1 = await cursor.fetchone() data2 = await cursor.fetchall() print(data1) print(data2) pool.close() await pool.wait_closed() if __name__ == '__main__': loop = asyncio.get_event_loop() loop.run_until_complete(test(loop))
(0, '古明地觉', 16, 'f') ((1, '椎名真白', 17, 'f'), (2, '古河渚', 20, 'f'))
我们看看可不可以使用tornado去启动aiomysql
import tornado.ioloop import aiomysql async def test(): # 这里的loop就是我们通过asyncio.get_event_loop()创建的,但是其实可以不传,因为会自动创建一个 async with aiomysql.create_pool(host="localhost", port=3306, user="root", password="zgghyys123", db="satori") as pool: async with pool.acquire() as conn: async with conn.cursor() as cursor: await cursor.execute("select * from girl") data1 = await cursor.fetchone() data2 = await cursor.fetchall() print(data1) print(data2) pool.close() await pool.wait_closed() if __name__ == '__main__': tornado.ioloop.IOLoop.current().run_sync(test)
一样是可以的,因为tornado的底层事件循环使用的便是asyncio
aiomysql还可以和SQLAlchemy结合
